What about rust? and dents?
Jul 20 2006, 8:13 PM EDT
If there's rust what is a good way to fix? Sand it down? I have some stuff I bought that's in a blue bottle that turns the rust kinda white looking and supposedly makes it paintable, any thoughts on this? I'm thinking of using your method to paint and old truck I'm fixing up to drive, I keep getting quotes from $4000 to $7000 to paint it, I just wanna drive it and have it look nice, not show it at World of Wheels ya know.

One way to treat rust is to knock off any loose flakes, and give it a good bath in phosphoric acid. The phosphoric acid reacts with the iron oxide and neutralizes the chemical reaction that makes rust. There are several brand names (Metal Ready, Ospho, Naval Jelly) but as long as the active ingredient is the same the results should be similar.
Since rust is what happens when sheetmetal is exposed to moisture, it is probaly best to thoroghly dry the rusted area, treat it, and then seal it with a top coat it asap. 1 out of 1 found this valuable. Do you? |

Rust, if its surface, should be sanded to bare metal, It it's rusted through you need to replace the metal with new welded in metal. Dents, if they are small enough, can bell filled with bondo. sand the bondo down to the body panels original line(surface level), then paint as you would noramlly.

In my opinion, it is best to grind/sand the rust away, then bondo , then primer, then paint the area. It has been my experience that the "rust converter" products create a plasticoat type of seal, but that the seal is not at all permanent.It does take a bit longer to grind/bondo/primer/paint, but not a whole lot longer -- especially if the rust does come back. --Mark http://www.marksatterfield.com 2 out of 2 found this valuable.
